Attrezzatura informazioni:

The Model 220 is a programmable current source with full
range current from 2nA to 100mA. The Model 220 has a
selectable voltage compliance of up to 105V in one volt increments.
The 100 memory locations allow up to 100
storage points for programming source, V-limit, end dwell
time. The Model 220 can be used with any measurement
system that uses the IEEE-488 interface bus. For detailed
